Berkeley DB versions reduction

Goal description

This goal pursues having just a one Berkeley DB shared library version per Debian stable release and have a support for migration from oldstable to stable. This release goal could be kept for all releases, the versions of the Berkeley DB libraries will change though.

Current status

There are db4.7, db4.8 and db5.1 in the unstable.

[2011-04-06] Bugs tagged with db5.1 are included in this goal db5.1 bugs

[2011-04-20] db4.7 dropped java support because it was broken on several architectures anyway and only lucene2 depended on libdb4.7-java

[2011-04-21] db(5.1) is waiting for ca-certificates-java to be installable again (#623672), the amd64 package was built using custom ca-certificates-java (since it doesn't build depend on it, it's just a dependency of a jdk)

[2011-04-25] I have NMUed ca-certificates-java and fixed src:db on non-openjdk platforms, all db packages are waiting for migration to testing

[2011-05-02] Dropped ability to link to generic -ldb from src:db4.7 (perl 5.12 was uploaded to unstable)
